A very hot, humid, and unstable air mass was in place during the daytime hours of August 5th, with the upper level ridge of high pressure centered over much of Texas. As a result, isolated showers and thunderstorms developed during the mid and late afternoon across portions of North Louisiana, Southwest Arkansas, and East Texas.

The episode as NWS SHV wrote it up.
A very hot, humid, and unstable air mass was in place during the daytime hours of August 5th, with the upper level ridge of high pressure centered over much of Texas. As a result, isolated showers and thunderstorms developed during the mid and late afternoon across portions of North Louisiana, Southwest Arkansas, and East Texas. One thunderstorm did briefly become severe over portions of Central Shreveport in Northwest Louisiana, which resulted in damaging downburst winds which blew down a large tree onto two homes. These storms quickly diminished shortly after sunset.

.DISCUSSION...
Saturday will appear to be quite similar to today. The only exception
is that isolated afternoon convection will be more widespread as the
upper level ridge that has kept most of the region dry, will
continue retrograde westward. This will allow for afternoon
convection to develop around it. Although more convection is
possible tomorrow, heat indices have been reaching
Warning/Advisory criteria by 1 pm the past few days before
afternoon convection develops. Therefore, the current Heat
Advisory and Excessive Heat Warning for today will be maintained
until 7 PM Saturday. Temperatures should once again warm into the
upper 90s to low 100s and high humidity values will combine with
the temperatures will result in heat index values above 105
areawide and likely above 110 across the eastern half of the CWA.
During the weekend and going through the middle of next week,
expect rain chances to continue, as the upper ridge will weaken
slightly and very slowly move into the Southeast CONUS. Northerly
flow will develop across the region which could bring weak complexes
of convection into Southern Arkansas and Northern Louisiana during
the early morning hours followed by possible redevelopment along
remnant outflow boundaries during the afternoon. In addition, a
series of weak disturbances rotating underneath the ridge could
also provide some higher rain chances. One feature that will
require monitoring is the possible development of a cut off low
over the northern Gulf just south of the Florida panhandle. Medium range
models has it drifting slowly to the west through the end of next
week. The models have been somewhat inconsistent with this
feature, so too many different solutions at this time to know how
it will affect our weather.
There appears to be no significant relief from the heat for the
next seven days. A couple of slightly cooler days might occur due
to increased cloud cover, but humidity levels are expected to
remain high especially over Louisiana and Southern Arkansas. This
should keep heat index values near or above 105 degrees for much
of the next week. /20/
